The XA5312 is a DC-DC converter with Current-Mode control and three optional operation PWM frequencies. Low 0.21V feedback voltage, Over Voltage Protection, Over Current Protection,Schottky diode open/short protection and inductor-shorted protection make XA5312 to be an ideal controller for LED backlight driver.

Internal soft start function can avoid inrush current happened in the start-up period. Additional Over-Temperature-Protection and UVLO make system more reliable. CMOS process greatly reduces the operating current when comparing to similar products.
